SPECIFICATION forming part of Letters Patent N 0. 636,521, datedNovember '7, 1899.

Application filed June 22 1899. $eria1 No. 721,447. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH GUEST, a resident of Homestead, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Rolling Metal; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to the making of angle-bars and plates therefrom,its object being to provide for the rapid reduction of the metal fromlarge ingots or billets, so as to produce with few passes two angle-barsat one time, and in addition, if desired, to provide for the formationof two flat plates or bars from each such angle, so providing for therolling of this class of articles by few passes.

The invention consists, generally stated, in

reducing a square billet first to star shape and then shearing thestar-bar into two angle-bars, this being preferably accomplished byforcing the opposite faces of the opposite flanges into line with eachother and then shearing in line with such opposite faces of ing thedifferent sections of the metal in course of reduction, and Fig. 10 is aface view of rolls suitable for forming the same.

Like letters and numerals indicate like parts in each of the figures.

In practicing the invention as shown in the drawings the square ingot orbillet a is rolled to substantially the form shown in Fig. 2, having itsoutwardly-extending flanges b, with partially-developed flanges c,midway on each side thereof, and in the next pass thepartially-developed flanges care brought into flange shape, producing astar-bar, as shown in Fig. 3, having flanges at right angles to eachother, as shown at d d d (1 By one or more passes the flanges onopposite sides of the bar are drawn out of line with each other, asshown in'Fig. 5-that is, say the flange on one side is forced downwardlyand the flange on the other side forced upwardly until the upper face eof one flange d is brought into line with the lower face f of the flanged, the flanges d and (1 remaining in line with each other. The next passof the rolls is constructed so as to sever the starshaped bar so formedalong the line of the faces of of the flanges d d and so form the twoangle-bars, one being composed of the flange d and the flange d and theother composed of the flange d and the flange (1- It thus requires fiveor less passes to reduce the metal contained in the square ingot intotwo separate angle-bars, while in so rolling the same the metalcontained within the bars in their different forms is so disposed as tobalance each other and prevent the bar from stretching unevenly and sobeing forced out of straight or proper line. In so reducing the bar itmay be desired to employ an intermediate pass, suchas shown in Fig. 4,before bringing the blank to the shape shown in Fig. 5 and ready to besevered into two angle-bars. The angle-bars so produced can be used asangle-bars, being given one or more finishing passes, if necessary, orcan be utilized in forming other shapes, such as by spreading out theangle-bars, as shown in Fig. 7, and then forming flat plates or skelptherefrom, as shown in Fig. 8, or, if flat plates or bars of less widthare desired, the anglebars, such as shown in Fig. 6, can be severedclose to the connecting-angle k and two bars Z m produced therefrom, asshown in Fig. 9, in this way providing for the formation of four or morerectangular bars from the original billet by very few passes.

In Fig. 10 are shown rolls with an arrangement of passes suitable forpracticing the method above described, the desired passes for such workbeing shown at 1, where the billet is rolled to the form shown in Fig.2, 2 and 3, where-the star-bar is produced, and 4, where the oppositeflanges are drawn out of exact line with each other-that is, so thattheir opposite faces 6 and f will be drawn into line with each other, asshown in Fig. 5-5 showing the pass for severing the star-bar into twoangle-bars. The passes 6 and 7 illustrate the flattening of said bar toproduce wide plate or skelp, while the pass 8 provides for the severingof the an gle-bar into two narrow bars which can be finished, ifdesired, in the pass 9.

The ad vantages of the invention should be apparent to thoseskilled inthe art, as it provides for the rolling of two angle-bars at one timeand overcomes the necessity of so great reduction from the originalbillet, providing for the production of such angle-bars in five or lesspasses and providing for the production of two flat bars from each angleby a single extra pass or for the opening out of the angle-bar into flatplate or skelp by one or more single passes. The cost of rollingistherefore very materially reduced.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The method of rolling angle-bars, consisting in reducing a squarebillet to star shape and then shearing the star-bar into two angle-bars,substantially as set forth.

2. The method of rolling angle-bars, consisting in reducing a squarebillet to star shape and forcing the opposite faces of two oppositeflanges into line with each other, and then shearing along the line ofsaid faces through the other flanges of the star-bar, so forming twoangle-bars, substantially as set forth.

3. The method of rolling flats, consisting in reducinga square billet tostar shape, and then shearing the star-bar into two anglebars, and thenshearing the angle-bars so produced along the line of the angle and soforming two flat bars from each angle, substantially as set forth.

4. In the rolling of angle-bars, rolls having passes arranged to form astar-bar, and a pass to shear the same at its meeting angles into twoangle-bars, substantially as set forth.

5. In the rolling of angle-bars, rolls having preliminary passesarranged to form a starbar, then a pass arranged to force the oppositefaces of two opposite flanges into line with each other and a succeedingpass arranged to shear through the bar in line with said faces,substantially as set forth.

6. In the rolling of angle-bars, rolls having passes arranged to form astar-bar, and a pass arranged to shear through such star-bar at themeeting angles and form two angles, and a pass to shear through suchangle-bar close to the angle thereof, substantially as set forth.

'7. In the rolling of angle-bars, rolls having passes arranged to form astar-bar, and then a pass arranged to shear through such starbar alongthe line at the meeting angles and form two an gle-bars,and then passesarranged to flatten out such angle-bar into flat plate, substantially asset forth.

In testimony whereof I, the said JOSEPH GUEST, have hereunto set myhand.
